Answer:

A self-referential formula defined by Jeff Tupper that, when graphed in two dimensions, can visually reproduce the formula itself.

Tupper’s self-referential formula which when graphed in two dimensions reproduces the formula itself.

Jeff Tupper’s Self-Referential Formula

When graphed, it’s output IS the formula used to do the graphing in the first place.

It plots itself.

It generates itself. (Tupper’s self-referential formula)

Tupper’s self-referential formula that graphs itself. There is a similarly awesome self-referential test here – http://www.brandonbray.com/fun/test.html

self-plotting formular (by tupper)

Tupper’s self referential formula – when programmed to graph this formula, one would obtain this formula

When graphed, this formula looks like itself! Self-graphing formula FTW (this is from a past SIGGRAPH paper)

Tupper’s self-referential formula. The graph of this formula is the formula itself.

Tupper’s self-referential formula. The equation when plotted on graph sheet can visually reproduce the formula itself. It is Math Quine!

Tupper’s self-referential formula is a self-referential formula defined by Jeff Tupper that, when graphed in two dimensions, can visually reproduce the formula itself.

It is the self-referential equation, which if plotted graphically gives the image shown.

Jeff Tupper’s self graphing formula. Formula can graph itself as an image in 2D

Equation describing Conway’s Game of Life.

The plot of the formula is the formula itself – self-referential formula.

Looks like a cellular automata that spells out an equation and evolves to the state of its own answer

A mathematical quine function? One that plots itself on the cartesian co-ordinates.

Tupper’s self-referential formula.

Formula plotted on a graph, plots itself.

Super qstn.

The formula plots itself.

Self referential formula – when graphed in x-y plane gives the formula itself.
